thermal Flashcards
1
Q
equation state for ideal gas
A
pv = NRT
2
Q
always work in
A
kelvin (then convert to degrees)
3
Q
on why pressure increases w/ temp
A
-avg kinetic energy increases
change in momentum (during a collision) is greater rate of change of momentum is greater (1)
(hence) force/pressure (during collision) is greater (1)
4
Q
why pressure greater with more powder in tube that has air pumped in
A
-p inversely proportional to volume
-volume air less with powder present
